Bottom line

Onitsuka Tiger Serrano Slip-Ons are true vintage models with just a hint of modern elements thrown in to make them more adaptable to the times. The slip-on characteristic makes the shoes easy to put on and off, yet keeps them snug and secure on the feet when they need to be, even without the use of laces. 

Because the shoes are so lightweight, they can be easily packed and taken with you when you travel. And belying that thin and light frame is a supportive profile that provides great footing during hikes and walks.

Onitsuka Tiger Serrano Slip-Ons are unisex. The size is based on men’s measurements, which run from 4 to 13. This is equivalent to women’s 5.5 to 14.5. 

The sneakers run large by about a half size, so men are advised to go down a half size. Women, meanwhile, need to adjust by taking off two whole sizes from their usual sneaker measurement. (There is usually a 1.5 size difference between men’s and women’s shoes. Since these kicks run large, we advise taking off two sizes for the perfect fit.)

The shoes do not rely on laces for a secure fit. The eyelets are purely for design purposes.

Thin suede and textile materials cover the uppers and may not look much, but these actually provide ample lateral support. The footbeds are cushioned but don’t offer much arch support. 

Just like the shoes’ ancestors, the Serranos, these slip-ons carry a certifiable vintage feel. The shoes are simply but beautifully-styled. Only the play of texture between the suede and textile fabrics and the contrasting Tiger stripes provide the main design feature against such a minimalistic background. 

Flat and thin soles give a hint of the shoes’ running-inspired build. And because they look so classic, they are easy enough to pair with many types of outfits, ranging from sporty to laidback to preppy. 

Onitsuka Tiger Serrano Slip-Ons come in blue smoke/indigo blue, white/black, light sage/black, evening sand/cream, and mid grey/cream colorways, among others.

Although bereft of any newfangled tech that usually accompanies current sneaker releases, Serrano Slip-Ons still boast of superior comfort that can meet the modern times’ high standards. The shoes can go head to head with many contemporary footwear—yes, even those chockful of modern tech—when it comes to weight, support, quality, and comfort. 

Style is nothing to sneeze at as well. The minimalist design taken from the original Serranos is still as relevant as ever and looks to still be so years down the road.

Serrano Slip-Ons are relatively new releases from Onitsuka Tiger, a distinguished Japanese brand with more than seven decades of footwear manufacturing history. These slip-ons are derived from the Serrano model which debuted in 2011. 

Serranos contain elements that were inspired by 70s track shoes, and this can be seen in the spiked rubber outsole design and lightweight build. The style was so eye-catching in its simplicity that Serranos have become one of the OT brand’s bestsellers.

Onitsuka Tiger decided to recraft the lace-up Serranos into slip-ons by adding a few details to keep the shoes snug and secure on the feet without the use of laces. The build and profile have largely remained the same.

  • Onitsuka Tiger Serrano Slip-Ons have uppers made of suede and textile, EVA midsoles, and rubber outsoles.
  • Each shoe weighs around 255 grams.
